IMPROVEMENT IN FLIERS IOhR SPINNING.

To all whom it may concern.- v

Be it known that we, S. A. B. ABBOTT, of Boston,

in the county of Suffolk, and State of Massachusetts,

chinery7 of which the following is a full, clear, and

exact description, reference being had to the accompanyingdrawings, making part of this specification, in which- Figure 1 is a perspective view of a flier, with our improvements applied thereto. Figure' 2 is a plan of the same.

Eigure 3l is a vertical section on the line xx of g.- 2.

lOur invention relates t'o certain improvements in the ordinary ily or Hier, which winds the roving upon the bobbin, by which it is twisted; and

Our invention has particular reference tothe connection of the presser-carrying rod, with the weight at its top.

The vertical rod and weight above referred to have been connected, by bending up the upper end of the rod, at right angles, or nearly so, and inserting it within the lower end of the weight, but this .method of attachment is objectionable for the followingreasons,v1z: l

. As the turns of the roving on the spool'increase in number, the pressure thereof, outward on the nger or foot, causes the weight to be brought so forcibly against vthe side of the upper part of the flier, as fre-l quently to bend the upper end of the rod, and incline the weight from the vertical, thus allowingthe lower cnd or presser-foot ofthe rod to lbe thrown out snflciently to cat'ch into that of the next'i'li'er, revolving in a contrary direction, thereby breaking or'tear-` ing the rods out o'f their weights, and .necessitating cpnstantrepairs, which are not only expensive, but

"difficult 'and tedious toper-forrn.

And the bent portion of the rod has alsobeen' inserted through an elongated .slot in the lside of the weight, and the weight mounted-on the top of the vertical bent part, in the same manner asp-when' the rod was secured to thebottorn of the weight, but lthis last arrangement stillleaves Ithe bent rod subject to' be bent by the actionof the centrifugal force of the weight, and it'is liable to-be-bent, and the weight to be thrown from -it's vertical position.

By our new device, or mode of fastening, the rod passes at right angles into lthe centre and ,side of the weight, and into a hole, in which it iits snugly,

and is secured without allowing any play, either laterally orwertically, tllus avoiding the possibility of being thrown from its true position by the centrifugal force.

To enable others skilled in the art to understand and use our invention, we vwill proceed to describe the manner in which we have carried it out.

A represents a ily or flier, which consistsv of two vertical portions, oriarrns a, b, connected by and forming a part of the central portion c, which bridges over them horizontally, or nearly so, one arm a being hol'- low, for the purpose ot' containing the roving, the other arm b being solid, to counterbalance the first during the revolution of the iiier. p

Projecting from the centreof the upper side of the bridge-portion c isa hollow cylindrical or conical boss, d,by which means the flier is iitted to the spindle, (not shown,) so as to 'revolve with itv B is a rod, of small diameter, passing tlxroughand turning loosely within guides or bearings e e, soldered orotherwise secured to or forming a part of the hollow arm a` of the flier.

-The upper end of this rod, justA above the upper guide c, is bent around under the centralporti'on of the hier, and is provided with a screw-thread at its extremity, over which is turned a weight, O, which is provided withva screw-thread ofv corresponding size for its reception, the rod entering the vside of the from f to-g, which serves as a presser-foot or blade,

the broad surface of which presses the roving com- Vpactly and evenly upon the bobbin, Athe distance of the weight G from the centre of revolution being care? fully regulated, and the relation of the weight to the rod being such as to insure the proper degree of press- `nre of the presser-foot upon the roving.

When the flier is revolving at a high' rate of speed, and the bobbin is nearly filled with the roving, the presser-foot is .pushed outwardly thereby, so' as to bring the side of the weight in contact with the side vof the central or bridge portion c, but,.owing to the straightness of the rod', and its 4c onnectioimvith the side of the weight, at or near its middle, the rod does not bend, nor does the weight incline, but they rigidly retain -their original position, thus preventing vtwo presser-feet from engaging with'each other,'and brea ing the respective parts to which they are connected.

By the old method of uniting, when the rod is broken, the bearings e c r'nust first be unsoldered and removed from the arm a; then the rod must be taken from itsk bearings, and a straight piece welded to the lower end of the rod, after which itis replaced within its bearings, and its upper end carefullyvbent, rst nearly or quite horizontally, then 'more abruptly in about a vel-tical direction, and thenattache'd to the cent-re of the bottom of the Weight, when nally the bearings are resoldered in place, which operations consume much time, beside being inconvenient and expensive.

It will be seen, from the foregoing, that the causes incident to the old construction, which produce the breakage of the part-s, are by our improved method of connection entirely removed.

Furthermore, the broken rods of the oldc'onstruction may thereby be readily repaired at a small oost.

It is evident that the end of the rod, instead of screwing into the Weight, may be pointed, and simply be driven in or soldered thereto.
